CLOCK-OAS E.

ATION Application filed Se tcinber 25, 1885.

To all whom it may concern:

Be it known that I, EDWARD M. JUDD, of \Vallingford, in the county of New Haven and State of Connecticut, have invented a new Improvement in CloclcCases; and I do hereby declare the following, when taken in connec tion with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a front view, half in vertical section; Fig. 2, a top view of the base, the divided section removed; Fig. 3, a horizontal section through the divided section of the body of the clock on line can of Fig. 1; Fig. 4, a lower end view of the one portion A of the divided section or body, showing the projecting lugs adapted to enter the cavities in the base; Fig. 5, a vertical central section through the base, the one portion A of the body section and the crown cutting through the lugs and recesses in the body-section, base, and crown; Figs. 6 and 7, modifications of the lug and recess; Fig. 8, a transverse vertical section cutting through the portion A on line .2 z of Fig. 1 and through the lugs in the crown and base, which wedge against the under side of the back of portion A.

This invention relates to an improvement in that class of clock-cases which are made from cast metal, the surface to be ornamented in imitation of various materials, generally marble, and particularly to that class which are made in several sections, and in which one or more of the sections are in two or more parts transversely-that is, the division between the parts being vertical. Parts ofclockcases thus made are secured together by bolts, the parts of the sections which are divided vertically by transverse or horizontal bolts,wliich serve to bind them togetherso as to form substantially one section, while vertical bolts will secure the several sections. For illustration, in Figs. 1 and 3 the body of the case is shown as formed in three sections, A, B, and O, the division between them being vertical, the cen tral portion, B, with its sides closed, and the side portions, A and G, abutted against the sides of the central portion, B, to complete the body portion of the case.

structcd these three parts are secured together As heretofore conpart of Letters Patent No. 340,950, dated 'April 27, 1886.

Serial Xo. 178,1 5. (Mullet) by transverse bolts, so as to become united as one section. Such an arrangement to secure the parts together complicates the case to a very great extent, and correspondingly increases its cost. The several sections are finally secured together by vertical bolts, and in order to form close joints between the parts numerous bolts are necessary for such purpose.

The object of my invention is to simplify the construction and construct the case of the clock so that one or two vertical bolts only need be required to secure the parts together and insure perfect joints between them; and it consists in the construction as hereinafterdescribed, and particularly recited in the claim.

In the illustration the base of the clock is formed in three sections, D, E, and F. These are molded to present any desirable or ornamental shape. Each part is provided with lugs to interlock with corresponding recesses in the adjacent parts, as seen at a and I), Fig. l. The central part, B, of the body is set upon the base, and then the two side portions, A 0, set against the respective sides of the central part, B, and as seen in Fig. 3.

In order that the parts A and C may be brought into close contact with the sides of the central part, B, and there securely held, l construct the base portion with cavities (2 upon its upper surface, and preferably near the angles, where the lower ends of the side pieces are to rest, and at corresponding points on the lower edge of the side pieces, A O, I construct lugs 6, corresponding to said recesses (Z, the outer side of the recess (1 inclined outward, as seen in Fig. 5, and the lug may be also correspondingly inclined. At the upper end the side pieces are constructed with similar lugs, f, and the crown-piece G of the case with corresponding recesses, g, as also seen in Fig. 5, the recesses and lug being correspondingly inclined.

The parts A and G of the body are set upon the base, to bring the lugs 8 into the recesses d in the base, and then the crown is set over the body, bringing the lugsf into the recesses Then vertical bolts H, one or more, are introduced between the crown and base to draw the parts vertically together. In such drawing of the parts together the crown por- ICO tion is forced upon the body portion and the body portion upon the base, causing the lugs at the bottom to enter the recesses in the base each other.

and the lugs at the top to enter the recesses in the crown, and because of the inclination between the lugs and recesses the downward draft upon the crown produces a wedge-like action upon the side pieces, through the said lugs and recesses, tending to wedge or force those side portions toward the central portion of the body and bring them to a close tight bearing against the sides, and so that the vertical bolts alone will serve to bind the parts together without the interposition of screws or transverse bolts.

The inclination of the lugs or recesses to produce the required wedging action may be entirely on the lug, as seen in Fig. 6; or it may be entirely in the recess, as seen in Fig. 7. In either case there will be the same wedgelike action to force the parts horizontally together.

The side portions, A O, are necessarily cast open inward or toward the central portion. This necessity arises from the difficulty or expense in otherwise molding the parts. The front and back are liable to turn inward in cooling, or from other cause to be turned inward out of their required parallel plane with To bring them intosuch required parallel plane, I construct the base upon which the side portions set with a wedge-like upwardly-projecting lug, h, (see Fig. 8,) and the crown with a correspondingly downwardlyprojecting wedge-like lug, 2', these lugs being adapted to enter inside the back Z of the side portions. These lugs, as the, parts are drawn together, will tend to spring the back of the side portions outward and into the plane of the back of the base and crown, and so that the whole back surface of the case will be flush.

By my invention as thus described I am enabled to make sections of clock cases divided into numerous parts vertically, yet bring them together for close and perfect joints and in a strong union with vertical bolts only.

I have shown but a single style or pattern of case in the illustration of myinvention; but this will be sufficient to enable those skilled in the art to which thisinvention pertains to construct various designs for cases in which the sections may be advantageously divided vertically.

I am aware that clock-cases have been made from cast metal, consisting of a base and an upper section, with the walls of the case made in part-s and introduced between the upper and lower section,with vertical bolts to secure the parts together. I therefore do not wish to be understood as claiming, broadly, such a construction of clock-case.

I claim The herein-described improvement in castmetal clock-cases, in which one or more of the sections are divided vertically into parts or portions, the said parts or portions arranged to rest upon a section below and support a section above, the said upper and lower sections constructed with wedge-like lugs h, adapted to bear upon the inner surface of the front or back of said portions, and the surfaces of said section and corresponding ends of the portions constructed one with recesses and the other with lugs to engage said portion with the respective sections, combined with vertical bolts, whereby the said several sections may be drawn together and upon said portions of the divided section, substantially as and for the purpose described. 1
